The amount of energy used in the lifetime of a building depends largely on construction methods and materials. The property sector accounts for around 18 percent of greenhouse gas emissions in Sweden, and there is significant room for innovation in the building sector.

Low-energy light bulbs without mercury

With the aim of developing a low-energy light bulb which works without mercury, Russian scientists and scientists from Chalmers University of Technology in Sweden have worked together to develop a field emission cathode, a cold cathode which produces a flow of electrons. The benefit over traditional hot cathodes is the reduction in heat loss. Hot cathodes can be found...

Heating systems to safeguard the future

The old oil-fired and electrical boilers used for heating homes really are past their sell-by dates – both from an environmental point of view and in light of the rising fuel prices. Some households have gone over to heating systems based on renewable energy, or have linked up to district heating networks. What may a smart future heating system...

Passive houses

The idea behind a ”passive house” is that it does not require a traditional heating system run, for example, on oil, wood or electricity. Instead, the energy should come from other heat sources, such as fridges, cookers and computers, and by utilising solar radiation. These heat sources may be supplemented by other measures which minimise the heat loss from...

Houses for the future

Energy- and resource-efficiency are important ingredients when buildings are planned, designed and built. There is no real conflict between attractive architecture, a sound indoor environment, energy-efficiency and reduced environmental impact, but architects and engineers must choose environmentally-adapted options. If a house is to be built with the environment as a central consideration, environmental sustainability must be part of the...
